Crews worked to extinguish the blaze from the outside of the building due to heavy fire conditions had it knocked down in about 20 minutes and kept it from causing major damage to the adjoining businesses, Heartland Fire & Rescue spokesman Sonny Saghera said. One firefighter suffered a minor injury and was taken to Grossmont Hospital to be evaluated.

Lake Murray Boulevard was closed in the immediate area, but was later reopened, according to La Mesa police.
